Driver's side window part help

[yours_falsely]

Alrighty, so back in october of last year Optimus (my yaris) was broken into for the head unit. Driver's side window was smashed completely. The next day I got it replaced and re-tinted. However for the past few days driving back and forth from college and home I was hearing a strange kinda thumping/clicking sound from the driver's side door. Today, I go to let my window up and about 4 inches from the top it shifts. couple hours go by and I go to let it down and It won't budge. Long story short (not really), the two white plastic pieces that attatch the window to the regulator broke. the regulator's fine but without those two pieces, I can't even get it to stay up. Any idea what those pieces are called? I'd rather fix it myself than go back to the auto glass shop. Thanks as always.
